First, I own a beater. She's not pretty but works for me. Lately my lift arms will slowly drop when the tractor is shut down. I am guessing the piston under the top cover needs work? Second, when the lift arms are raised to top when tractor is running I get a bouncing up and down with equipment attached or not. I think I should pull the cover and drop the pump and do a rebuild. Suggestions anyone? Does anyone have a nifty way to remove the arms from the pump when it is dropped and to re-attach? This tractor looks pretty simple but I am sure something is gonna bite me unless I ask questions. Thanks for any help.
